Specification of Letters Patent.

Patented June 3, 1919'.

Application filed April 29, 1918. Serial No. 231,483.

To all whom it may concern: 7 I

Be it known that I, CLARENCE E. FLINoH- Bacon, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented new and useful Improvements in Windmills, of which the following is a specification.

This invention relates to Windmills, the broad object in view being to increase the power efliciency of a windmill at the same time reducing the wear and tear on the working parts of the windmill, and thereby increasing the life and durability thereof.

One object of the invention is to'equalize the strain and wear on the main rotary wind wheel shaft thereby producing a smoother acting mill and a corresponding decrease in vibration.

Another object of the invention is to provide a novel and particularly efficient form and arrangement of rudder or vane. 'Its vertical. construction avoids overhanging weight on the rudder post; also gives the air current free access to a portion of the rudder which extends above the wind wheels. Said wind wheels consist of one in front and one in the rear located on opposite sides of the vertical shaft which is rotatably sup-" ported by the tower'or main frame structure of the machine.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings:

Figure 1 is a side elevation of the improved windmill.

Fig. 2 is a top plan view thereof.

Fig. 3 is a vertical cross section taken between the wheels, showing the gearing of the mill.

Fig. 4 is a detail perspective view of the rudder and a part of the operating connections thereof.

Referring to the drawings, A designates generally the tower or supporting structure of the windmill which may be of any usual or preferred formation. 1 designates the bearing yoke which is supported upon the upper end of a vertically disposed shaft 2 which is journaled in the head section 3 of the tower and has fast thereon a collar 5 which provides an annular supporting shoulder bearing against the cap or top section 3,

enabling the yoke 1 to turn freely on a vertical axis in accordance with the direction of the wind;

Journaled in a pair of upstanding arms 4 of the yoke 1 is the main wind wheel shaft 5. This shaft projects on opposite sides of the yoke 1 and has attached to the forward end thereof a front wind wheel 6 and has fast on'the opposite end thereof a rear wind wheel 7. It will be seen that the wheels 6 and 7 are arranged in spaced relation to each other, so that. the current of air may act equally on both wheels. 7

Fastened to the base portion of the yoke 1 is a beam 8 and secured to one end of said beam and extending upwardly therefrom is a rudder post. 9, said rudder post being fixedly secured to the beam 8. The beam 8 extends on the opposite side of the yoke 1 and is provided at the extremity thereof with an upstanding lug 10 to which is attached by means of a pivot 11 one extremity of a rocker arm 12. The opposite or free extremity of said rocker arm is connected by means of a pivot 13 to a link 14 which is in turn connected at its opposite end by means of a pivot 15 to the upper extremity of the upper section 16 of the pump rod, said rod being connected with the pump in the usual manner, not illustrated in the drawings.

Fast on the shaft 5 is a gear 17 which meshes with and actuates another gear 18 fast on a countershaft 19, parallel to the main shaft 5, and journaled in a countershaft frame 20 which forms an extension of the yoke 1. The gear 18 has a crank or wrist pin 21, to which is connected one end of a pitman 22, the other end of which is connected by a pivot 23 to the rocker arm 12, motion in this way being transmitted to the rocker arm 12 and by means of the link 14 to the pump rod 16. The rudder or vane 24 is provided on one side with upper and lower ears 25 through which the vertical rudder post 9 passes, the rudder being thus free to turn upon said post. Extending from the rudder 24 is an arm 26 to which is pivotally attached one end of a link rod 27, the other end of which is pivotally attached to one arm of a governor lever28, the latter being pivotally mounted at 29 on one of the arms 4 of the yoke 1. One arm of the lever 28 carries a weight 30 and the extremity of the and throw the windmill out of action by disposing the wind wheels 6 and 7 edgewise toward the wind.

It will be observed that the rudder 24 is substantially L-shaped in elevation being cutaway at 33 to give clearance for the blades or wings of the rear wind wheel 7. This provides the rudder with an overhanging portion 31 which extends above the wind wheels 6 and 7 thus receiving full force of the wind with which to swing the windmill in and out of action.

By reason of the construction and arrangement hereinabove described, it will be seen that the wear and strains on the propeller shaft are distributed and equalized as the weights of the two wind wheels are preferably equal and they are located on opposite sides of the vertical axis on which the yoke 1 turns. A consequent reduction of friction on the shaft 5 is obtained and as the pressures on the two wheels are approximately equal there is little or no inclination for the yoke 1 to be turned in either direction. By reason of such equal distribution of the stresses and strains on the shaft 5, the windmill as a whole may be built in large sizes, thereby enabling proportionately greater power to be generated thereby.

I claim:

1. In a windmill, a main rotary wind wheel shaft, a bearing yoke in which said shaft is journaled adapted to turn on a vertical axis, front and rear wind wheels fast on said shaft at opposite sides of the vertical axis of movement of said yoke and arranged in spaced relation to each other, a reciprocatory pump rod geared to said shaft and actuated thereby, a substantially vertical rudder post connected with said yoke a rudder mounted for turning movement on said rudder post, and a weighted governor lever connected with said rudder, said rudder being substantially L-shaped in elevation to provide a portion which overhangs the rear wind wheel and provides clearance therefor. i

2. In a windmill, a main rotary wind wheel shaft, a bearing yoke in which said shaft is journaled adapted to turn on a vertical axis, front and rear wind wheels fast on said shaft at opposite sides of the vertical axis of movement of said yoke and arranged in spaced relation to each other, a reciprocatory pump rod geared to said shaft and actuated thereby, a substantially vertical rudder post connected with said yoke, a rudder mounted for turning movement on said rudder post, and a weighted governor lever connected with said rudder, said rudder having a horizontally projecting portion which extends across the periphery of the rear wind wheel.

In testimony whereof I aflix my signature.
